>( please show me an instance where a major car company sent 5% performance increase over the internet )
That doesn't sound like anything special. Engines have been computer controlled for a long time now. Depending on the temperature, fuel mixture, etc you can have a single engine with completely different characteristics. This is something VW took advantage of in Dieselgate by improving the performance of the car outside of emissions tests. If your car was affected the only thing that was changed by the recall was the software. Of course OTA updates are more convenient than driving to your dealer but software updates themselves are not a competitive advantage of Tesla.
